PURPOSE: A device for indicating an element with a fracture is provided to easily grasp the set clamping force by providing when the clamping force of a clamp reaches the set value and a space between the inner edge part of an end face wall and a cylindrical object reaches a specified space in a device for indicating the state of the clamping force of the clamp reaching the set value. CONSTITUTION: An indicating device(21) is provided for indicating that a set value of a clamping force of a tightenable clamp has been reached. The clamp has an approximately C-shaped clamp strip(1) with first and second circumferential ends facing one another in a circumferential direction of the clamping strip and axial ends extending in the circumferential direction from the first circumferential end to the second circumferential end. The axial ends have radially inwardly projecting end face walls with a radially inner edge. Clamping protrusions(4) are connected to the first and second circumferential ends. The indicating device has at least one breakable indicating element for each one of the end face walls(2), wherein the breakable indicating elements is placed onto the radially inner edge of the end face wall. The breakable indicating elements break when the set value of the clamping force of the clamp is reached and a predetermined spacing of the radially inner edge of the end face walls from a cylindrical object clamped in the clamp is reached.
